Function codes
Refer to Table 5-3 for a numerical listing of the function
codes. The table accurately represents the display of each
function code and identifies the security level for read, edit,
and reset, the factory setting, and the low and high limits
for keyed in entries. This is followed by a description and,
where appropriate, a list of scrollable choices, examples,
and related functions and features for each function code.

• The total operations counter is activated by detecting tap-changer motor operation, which is determined by sensing current
flow in the holding switch circuit.
• The total operations counter is written into non-volatile memory after every count.
• Access other operations counters at FC 100–FC 107.
1 Settings Forward Direction 001 Forward Set
Voltage
120.0 Volts
0 2 NA 120.0 100.0 135.0
• The forward set voltage is the voltage level to which the control will regulate, on the 120 V base, during forward power flow.
2 Settings Forward Direction 002 Forward
Bandwidth
2.0 Volts
0 2 NA 2.0 1.0 6.0
• The bandwidth is defined as the total voltage range, around the set voltage, which the control will consider as a satisfied
(in-band) condition, during forward power flow.
• Example: A bandwidth of 3.0 V and a set voltage of 120 V will establish a low edge of 118.5 V and a high edge of 121.5 V.

Time Delay

0 2 NA 45 5 180
• The time delay is the period of time that the control waits, from when the voltage first goes out-of-band to when a tap
change is initiated, during forward power flow.
• See FC 42, Control Operating Mode.

• The resistive line-drop compensation value is used to model the resistive line voltage drop between the regulator and the
center of regulation.
• The control uses this parameter, in conjunction with the regulator configuration (FC 41) and the load current, to calculate and
regulate to the compensated voltage (displayed at FC 8) during forward power flow.
